Abstract (en)
[origin: WO2016162015A1] The invention relates to a cooling unit (1) for cooling the air (10.3) admitted to the interior (101) of a switchgear cabinet (100), which cooling unit has an inner circuit (2), through which the air (103) to be cooled is routed from a switchgear cabinet interior (101), and an outer circuit (3),which is partitioned from the inner circuit (2) in fluid terms and through which the ambient air (104) is routed, wherein the inner circuit (2) contains a first heat exchanger (4) and the outer circuit (3) contains a second heat exchanger (5), which have a coolant (6) circulated between them, wherein the heat exchangers (4, 5) have an air passage direction (x, y) along which the heat exchangers (4, 5) allow air to pass between an air inlet side (4.1, 5.1) and an air outlet side (4.2, 5.2), characterised in that at least one of the heat exchangers (4, 5) has a first air guide element (16) upstream on the air inlet side (4.1, 5.1), which air guide element extends at an angle (ß), where 5 < ß < 45°, with respect to the air inlet side (4.1, 5.1) and forms an air duct (7) between itself and the air inlet side (4.1, 5.1), which air duct tapers along a dimension (z) of the air inlet side (4.1, 5.1).
